If you do this is very strange and you should recheck your build. Please provide the output of ident /sbin/hastd command. JK> and hast.conf configuration from both machines: JK> I've decided to put metaflush option on every single level just to be JK> sure. No effect. No need in disabling metaflush in your case. It will disable automatically after the first attempt failed. #################### end FreeBSD 9.0 was also released in january!, but i can not tell if this patch has made it into release 9.0 I think it does not. So if time permits, maybe try FreeBSD 9.1 which will proberbly be released any time now! regards and best wishes Johan Hendriks Neuteboom Automatisering
